Re it known that we, Guantes lV. VAN Dn Atmen and Ronniz'r T. J nNNicv,citizens ot' the United States, and residents ot Two Riv- 1 slotted at2O to embrace the lower end otl said ers, in the county of Manitowoc andState of `Wisconsin, have invented a new and Improved (iate, ot' whichthe Following is a full, clear, and exact description.

Our invention relates to gates, and more particularly to mechanism t'oropening and closing' the same. its principal objects are to provide a.simple and eti'ect-ive mechanism t'or this purppse.

lt consists in thc various Vfeatures and coinbinations hereinafterdescribed and claimed.

he terence is to be had to the accompanying' drawing-s, forming a partot' this specilication, in which similar characters ot' referenceindicate correspomling' parts in all the tigures.

Figure l is a perspective view ot' a portion ot a tence and a gateembodying' one forni ot' our invention. Fig'. '2 is an enlarged brokenelevation showing the gate in its open position. Fig. P) isa brokendetail` in top plan, otl the operating' mechanism. Fig. l is ahorizontal sectional detail showing the lower support ot' the gate; andFigs. 5, 6, and T are details in horizontal section illustrating.respectively. the position ot' the elements when the gate is closed,when it is in an intermediate position` and when open.

A tence is designated by the letter F, there being in said tence anopening' which is closed by a gate (l. .-\t one side of thegate-opening' is a post l), preferably extending somewhat above theheight ot the ordinary tence, and upon this post are mounted supports,here .shown as eyebolts lil, ll. l2. and 13, through the openings ot'whichextemls a vertical spindle li. A\bout this spindle swings the gate(i, this heilig here illustrated as consisting' otl an outer trameformed ot' bent channel-iron, furnishing top and bottom bars 1l and l5,respectively. and a vertical end bar lo. It is provided with horizontalmembers 1T, suitably spaced and extending through openings in the endbar and in a series ot' vertical members 18 and diagonal stays '19. Atthe inner end ot' the top bar is an opening which coperates with thespindle, and the lower bar is spindle, this slot being closed outsidethe spindle by some such device, as a Cotter Ql. The lower bar normallyrests upon the support lo; but it' it desired to raise. the gate so thatit may operate al1 a greater height to enable it, t'or example., to moveabove snow the cotter may be removed and the lower bar swung out,whereupon the upper bai' may be slid upon the spindle until the slot .20comes above the support ll, when it may be again brought intocooperation with the spindle and secured in place bythe cotter. Theupper supports l2 and 123 serve asa bearing tor the spindle, and thedistance between them is sutiicient to permit this transfer ot' the gateto the second support.

A latch is provided t'or the gate, here shown as consisting ot' aflexible metallic bar Q2, pivoted at 9.2 to the end ot' a bracket 23,lixed to the lower bar l and guided at its upper end by a continuation2l ot' one otl the horizontal members l T, this extending through a slotin the bar 22. A nut 26 is preterably threaded upon the end ot' theextension to limit the outward movement ol the latch. The upper end ot'the spring-bar 22 may have formed upon it a handle 2T t'or conveniencein operation by persons on t'oot. The latchbar may coact with aninclined catch 28, lixed at one side otl a post ,n at the opposite sideot' the gateopening from the post P.

At the side to which the gate is to swing', it being' situated atsubstantially ninety degrecs from the post p and at the same distancetrom the post l" as said post p. is a post or upright Q9, connected nearits upper end with the end ot' the post l by a cross-bar 3l). Thisupright 29 carries a catch 29 for engagement with the latch-bar '22 whenthe gate is open. VFrom each end ot' the cross-bar projects an arm 3l,here shown as inclined up-4 wardly therefrom at a slight angle and for lthe sake of strength and lightness consisting of opposite side pieces 3232, joined at their ends and connected by an intermediate crossbar orstay 33. They may each be braced by a diagonal stay 34, secured to thestay 33 and to the adjacent post. Fulcrumed at 35 upon the end of eacharm is a lever 36, at the outer extremity of which is a pendant 37,carrying a handle 38. From a point near the inner end of this leverrises a projection or arm 39, and these opposite arms are joined byconnectors or rods 40 to the opposite ends of an operating-lever 41,fulcrumed at 42 between the cross-bar 30 and a bracket 43, which may besecured to the post P at one end and to the cross-bar at the other. Therod 40, which extends farthest from the lever 41, may be supported by aguide 44, carried by the arm 31 at that side of the gate.

Fixed to the upper end of the spindle is an arm 45, which is connectedat its outer extremity by a link 46 to the lower end of the lever 4l,this arm and link together forming a toggle-lever. The arm may also byits contact with the support 13 serve to fix the position of the spindlein the support. Connected to the operating-lever between its fulcrum andthe point of attachment of the toggle is a spring 47, fastened at itsopposite end to the post P and exerting its force to maintain the gatein one or the other of its extreme positions, as will be hereinafterdescribed, and at the same time to hold the levers 36 raised. Theattachment of the spring to the post is preferably through a threadedrod 48, extending through an opening in said post and having at theouter side thereof a nut 49, the rotation of which will serve to varythe tension of the spring.

Fixed to the spindle at a point here shown as substantially midway ofthe gate is an arm 50, which is connected by a suitable link 51 to acollar 52, fast upon an operating member or bar 53, extendinglongitudinally of the gate. This bar is mounted to slide in the bar 16and members 18 and preferably passes freely through openings in thestays 19. At the opposite extremity of this bar is a threaded portion54, which extends through an opening in the latch and is lixed withrelation thereto by opposite check-nuts 55 55.

When the gate is closed, the toggle will occupy the position illustratedin Fig. 5 of the drawings. Now if it is desired to open the gate eitherof the handles 38 may be drawn downward. This depresses the lever 36 andthrough the connecting-rod and the operatinglever straightens the toggleagainst the tension of the spring, which results in a rotation of thespindle. This through the arm 50 and link 51 first moves theoperating-bar 53 from the spindle, releasing the latch-bar from thecatch 28, then the arm continuing its revolution swings the gate. Thisstraightening of the toggle is effective to move the gate until itselements are alined with one another, as is illustrated in Fig. 6; butthe momentum of the gate will be suflcient to swing it by thisintermediate point, which is at substantially forty-iive degrees fromits closed position, causing the toggle to break upon the other side.This brings the tension of the spring upon the gate in such a manner asto continue its movement, and this causes it to contact with the upright29, at which point the latchbar engages the catch 29u and locks it inplace, the operating elements occupying the position shown in Fig. 7.The closing of the gate may be accomplished in exactly the same manner,the toggle in this case merely moving in the opposite direction.

It will thus be seen that the gate may be operated in either directionfrom either side by a person in a vehicle and that at either of itsextreme positions it will not only be locked by the catch provided, butwill be held by the tension of the spring, which assists in opening orclosing it. The gate and its operating -mechanism is, moreover,extremely simple and durable.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. The combination with a gate, of a spindleabout which the gate may swing, an arm fixed to the spindle, anoperating-lever connected with the arm, a spring exerting its tensionupon the operating-lever, and means for transmitting the movement of thespindle to the gate.

4. The combination with a gate, of a spindle about which the gate mayswing, a lever, a toggle connecting the lever and gate, a spring actingupon the lever, means for adjusting the tension of the spring, and meansfor transmitting the movement of the spindle to the gate.
